YouIs the rateable value on my client's shop at Unit 4, Longfield Avenue, Ealing W5 fair? It's their only business property.

Your AI assistant

Strong case. The shop is valued at £390 per m². The median for 13 comparable shops within 5 km, in the same Valuation Office scheme, is £280 per m². It is about 39% above that, and above the range the scheme applies to 43 similar-sized shops (£202 to £365, median £284).

Rateable value now£69,500bill about £29,885

Suggested rateable value£50,100bill about £19,138

Indicative saving£10,747a year, before reliefs

Backdated to 1 Apr 2026£6,360so far this year

Checks. Floor area consistent with the energy certificate. No allowance gap against the 13 comparables. No small business rate relief at this value.

Route. Start a Check through the Valuation Office business rates account (assessment 29187286000) with the 13 comparables. If it is not agreed, Challenge within four months. Keep paying meanwhile: any reduction is backdated and refunded.

What-ifs. Agreed in full: about £10,747 a year. Halfway: about £4,171. A further 5% allowance: another £955. What-ifs, not findings.

This is an indication from comparable evidence, not a valuation. A Check or Challenge is a separate step you choose, and the Valuation Office may reach a different view; it can also correct facts that increase the rateable value.

Then “Write that up as a one-page note I can send to the client.” The assistant drafts the note from the same figures (see In your documents, below).
